Good morning, We've got a shiny new IBM cluster with e325 nodes (Opteron). However, we're having some trouble with a number of nodes. We keep getting 'GART' errors showing up in the logs. Here is an example, Jun 21 07:07:42 c3n32.cluster kernel: Lost an northbridge error Jun 21 07:40:52 c1n4.cluster kernel: Lost an northbridge error Jun 21 07:07:42 c3n32.cluster kernel: GART error 3 Jun 21 07:40:52 c1n4.cluster kernel: GART error 3 Jun 21 14:03:49 c1n2.cluster kernel: extended error chipkill ecc error Jun 21 14:03:50 c1n2.cluster kernel: corrected ecc error Does anybody have any ideas what the cause might be? Thanks! Jeff -- Dr. Jeff Layton Aerodynamics and CFD Lockheed-Martin Aeronautical Company - Marietta
